The smooth endoplasmic reticulum.
It is 'upstream contiguous' from the protein producing ribosomes located in the rough endoplasmic reticulum; as well, it is 'downstream contiguous' with the Cell's export assembly - the Golgi apparatus.
Proteins are specifically addressed as to their destination! Not all are Labelled for Export!
Do you mean what organelle, inside the cell, transports proteins from the RER to the plasma membrane?
"A ribosome only binds to the ER once it begins to synthesize a protein destined for the secretory pathway.[3] Here, a ribosome in the cytosol begins synthesizing a protein until a signal recognition particle recognizes the pre-piece of 5-15 hydrophobicamino acids preceded by a positively charged amino acid. This signal sequence allows the recognition particle to bind to the ribosome, causing the ribosome to bind to the RER and pass the new protein through the ER membrane. The pre-piece is then cleaved off within the lumen of the ER and the ribosome released back into the cytosol."

The organelle that transports the proteins is called a vesicle.
"Proteins that are destined for places outside the endoplasmic reticulum are packed into transport vesicles and moved along the cytoskeleton toward their destination."The vesicles because it contains and transports various substances such as protein
well, ribosomes make proteins within a cell, but mitochondria have proteins.
cannot make new proteins and will worn out within a few months
Every cell contains DNA within the nucleus, containing the blueprint to build many different proteins in the cell. Different signals can cause embryonic cells to select specific parts of the DNA which can then be used to synthesize proteins, eventually building different cell types.
They are used in Facilitated Diffusion, helping to transport ions, macromolecules, and other substances incapable of entering a cell by themselves to cross through the plasma membrane of the cell.
ribosomes make proteins and the endoplasmic reticulum transports materials through the cell
Golgi complex transports proteins and other things as well.It's organelle packages and distributes proteins.

The Golgi body
The Cytoplasm
The uniformity of cytoplasmic streaming refers to the movement of the fluid substances within the animal or plant cell. Cytoplasmic streaming transports organelles, proteins, and nutrients within the cell.
Ribosomes carrying proteins are exported from the golgi apparatus throughout the cell
The Golgi appartus stores, packages, and transports chemicals within a cell.
Golgi Apparatus
Golgi apparatus are the ones that are responsible for transporting proteins inside the cell. This is the case within eukaryotic cells.
It transports proteins and other stuff throughout the cell.
